Abstract

Introduction: Patients with congenital diaphragmatic hernias (CDH), omphaloceles, and congenital lung malformations (CLM) may have pulmonary hypoplasia and experience respiratory insufficiency.We hypothesize that given equivalent lung volumes, the degree of respiratory insufficiency will be comparable regardless of the etiology. Methods: Records of all fetuses with CDH, omphalocele, and CLM between January 2000 and June 2013 were reviewed. MRI-based observed-to-expected total fetal lung volumes (O/E-TFLV) were calculated. An analysis of outcomes in patients with O/E-TFLV between 40% and 60%, the most inclusive range, was performed. Results: 285 patients were evaluated (161, CDH; 24, omphalocele; 100, CLM). Fetuses with CDH had the smallest mean O/E-TFLV. CDH patients were intubated for longer and had a higher incidence of pulmonary hypertension. Fifty-six patients with the three diagnoses had an O/E-TFLV of 40%-60%. The need for ECMO, supplemental oxygen at 30 days of life, and 6-month mortalitywere similar among groups. CDH patients had a significantly longer duration of intubation and higher incidence of pulmonary hypertension than the other two diagnoses. Conclusion: Given equivalent lung volumes (40%-60% of expected), CDH patients require more pulmonary support initially than omphalocele and CLM patients. In addition to lung volumes, disease-specific factors, such as pulmonary hypertension in CDH, also contribute to pulmonary morbidity and overall outcome.
